- the advantage here is that the cooling air flow between the cooling fins can be carried out below the yoke or web when viewed from the housing part.
- the webs are spaced apart from one another and are arranged one behind the other along a straight line.
- the advantage here is that the cooling air flow can be passed through below the webs when viewed from the housing part, in particular in a direction parallel to the direction of the axis of rotation of the driving shaft.
- the webs arranged one behind the other along the straight line are identical to one another, with the exception of a first web, on which an eyelet is additionally formed, and a second web, on which an additional eyelet is additionally formed.

- each housing part is connected to two base plates.
- the first and/or input gear stage of the transmission is an angular gear stage and the cooling fins are parallel to the axis of rotation of the input shaft of the transmission
- the angular gear stage aligned, in particular wherein the driving shaft is aligned perpendicular to the driving shaft of the gear.
- the advantage here is that a fan can be driven by the driving shaft, which creates an air flow along the cooling fins parallel to the axis of rotation of the driving shaft
- a shaft end pump is arranged on a shaft of the transmission, in particular on an intermediate shaft of the transmission, and is driven by the shaft,
- shaft end pump is connected to a multi-way valve, in particular a three-way valve or two-way valve,
- - is optionally connected to a first oil pipeline, which runs through the wall
- the first housing part opens into a through hole, or is connected to a second oil pipe which opens into a through the wall of the second housing part through hole, in particular so that the oil can be sucked in by the shaft end pump from the oil sump of the transmission, in particular when the multi-way valve is in the appropriate switching state .
- the advantage here is that the shaft end pump sucks oil from the oil sump, with the gearbox being set up in the first or second orientation, i.e. either with the first housing part as the lower housing part or alternatively with the second housing part as the lower housing part.
- the second connection of the shaft end pump is connected via an oil line to an oil filter, from which a further oil line leads to a hole passing through the first housing part, in particular the first connection of the shaft end pump via a safety valve,
- the 20 in particular pressure relief valve is connected to the second connection of the shaft end pump.
- the advantage is that the oil is filtered.
- the oil filter is located on the outside of the transmission so that the oil is cooled.
- the base plates connected to the respective housing part are aligned parallel to one another.
- the advantage here is that a foot plate can be provided on each long side of the housing part. This allows for a stable setup.
- either the first housing part is arranged below the second housing part in the direction of gravity and/or the first housing part is placed with its base surfaces on a floor surface
- the gearbox 10 or the second housing part is arranged below the first housing part in the direction of gravity and/or the second housing part is placed with its foot surfaces on a floor surface.
- the housing of the transmission is shown in an oblique view from a first viewing direction.
- FIG. 1 A front view of the transmission is shown in FIG. 1
- the transmission has a housing composed of two identical housing parts 1.
- the gearbox can be set up inverted on the floor, i.e. rotated through 180°. Because each of the two housing parts 1 is included
- Each of the housing parts 1 is formed with cooling fins 3 on its outside.
- the housing therefore functions as a split housing.
- the bearing receptacles for receiving rolling bearings for the shafts of the transmission, in particular for the driving shaft, at least one intermediate shaft and the driving shaft of the transmission are also divided by the split plane, in particular with the respective half of the bearing receptacle in the first housing part 1 and the other half each is arranged in the other housing part 1.
- the webs 4 are preferably welded on the one hand to a respective base plate 2 and on the other hand to the respective housing part 1.
- the webs 4 surround the cooling fins 3 in such a way that the respective cooling fins 3 are between the
- the cooling fins 3 encompassed by the respective web 4 are spaced apart from one another and arranged parallel to one another.
- the cooling channels formed between the cooling fins 3 thus lead between the respective web 4 and the respective housing part 1.
- the webs 4 are arranged one behind the other along a straight line.
- the webs 4 are preferably designed to be identical to one another, although along the
- a first of the webs 4 additionally has an outwardly outstanding eyelet and a last of the webs 4 also has an outwardly outstanding eyelet.
- the foot parts protrude towards the floor over the housing part. Because the respective webs 4 are attached to the respective housing part 1 and hold the respective ones
- cooling fins are also formed on the side of the housing part 1 facing the bottom, which are spaced apart from one another and extend parallel, in particular perpendicular to the direction of the axis of rotation of the driving shaft of the transmission.
- the transmission housing composed of the two housing parts 1 therefore has cooling fins 3 on almost all sides. This ensures improved heat dissipation.
- an air stream can be guided along all sides of the gear housing parallel to the axis of rotation of the driving shaft and flows along between cooling fins 3.
- cooling vanes or cooling fins as they also increase the surface area.
- the wall thickness of the respective housing part 1 in the area of the bearing receptacles is larger, in particular at least five times larger, than the wall thickness of the housing part 1 in that area of the housing part 1 in which the cooling fins are arranged.
- the webs 4 are attached to these areas of the bearing holders, in particular
- the webs 4 therefore also protrude beyond the cooling fins into the surroundings.
- Each web 4 is U-shaped or has at least a U-shaped basic structure.
- the axis of rotation of the input shaft is aligned perpendicular to the axis of rotation of the output shaft.
- the first gear stage is therefore designed as an angular gear stage and the further gear stages are parallel shaft gear stages, in particular spur gear stages.
- the respective housing part 1 is designed to be beveled in the area of the first gear stage.
- the first gear stage is therefore preferably designed as a bevel gear stage.
- the slope on the front of the housing part 1 is designed in such a way that
- housing part on the front of the bearing holder for the bearing of the driving shaft with decreasing distance to the base plates 2 has a preferably strictly monotonically decreasing distance to the driving shaft.
- a shaft end pump is arranged on the first intermediate shaft of the transmission, i.e. on the output shaft of the first transmission stage.
- the oil flow conveyed by the shaft end pump is directed through an oil filter 21 and from there back into the oil sump of the transmission.
- the oil line required for this from the shaft end pump to the oil filter 21 is attached to the outside of the gearbox.
- the oil line from the oil filter back to the oil sump is also on
- a multi-way valve in particular a three-way valve, is attached to the outside of the transmission, so that the suction side of the shaft end pump 6
- the transmission can also be operated when it is rotated through 180°, in particular when it is turned upside down. Because then only the multi-way valve 5 has to be changed so that oil can be sucked in by the shaft end pump from the oil sump now located in the other housing part 1.
- a fan is non-rotatably connected to the driving shaft.
- An air guide hood 7 directs the air flow conveyed by the fan along the cooling fins 3, so that an air flow moves along all four sides of the essentially cuboid housing part 1.
- the fan cover 7 is preferably connected to both housing parts 1 and covers the slanted areas.
- the oil pipes and oil lines are preferably located in the air flow conveyed by the fan, so that the oil conveyed by the shaft end pump is also cooled.
- the suction side of the shaft end pump is connected to the pressure side of the shaft end pump 6 via a safety valve 20, in particular a pressure relief valve.
- the shaft end pump is operated in reverse in FIG. 6, so that the oil comes out of the oil sump of the first housing part 1, i.e
- Oil lines are preferably arranged in the interior of the transmission, which carry the oil supplied through the bore to lubrication points, in particular bearings and
